A "witch's broom" is a term used in botany to describe a dense cluster of twigs and leaves that grow at the end of a branch. This abnormal growth can occur in various plants, including trees and shrubs, and is often caused by factors such as fungal infections, insect infestations, or genetic mutations. The resulting structure resembles a broom, hence the name. In agriculture, witch's broom can be problematic as it may weaken the plant and reduce its yield. It is important for gardeners and farmers to monitor their plants for signs of this condition and take appropriate measures, such as pruning or pesticide application, to manage it effectively.
